In the above structure, the PLC control cabinet 33 is provided with a main controller 331, and the driving motor 312 of the self-priming water pump 31, the driving source of the vacuum pump 321, the electric butterfly valve 41, the pressure sensor 42, the drainage electric valve 3221, the first water level sensor 11, the second water level sensor 326, the drainage electric valve 328, the monitoring device 35, the flow meter 43, the intelligent controller 364, the wireless gateway 34, the external power source 37 and the remote communicator 38 are respectively connected with the main controller.
In the above configuration, the solar power system 36 operates continuously to charge the battery pack 362 or to power the intelligent control priming system. When the electric quantity of the storage battery 362 is more than 20%, all equipment of the intelligent control water diversion system can work; at 20% and below, the self-priming water pump 31 and the vacuum-pumping system 32 cannot be started, and the intelligent controller 364 can send an alarm signal to the main controller 331 arranged in the PLC control cabinet 33. The PLC control cabinet 33 is provided with a main controller 331 which transmits a signal of "insufficient electric quantity, unable start-up" to a network terminal through the remote communicator 38 and the wireless gateway after receiving a signal for turning on the external power supply. After receiving the signal, the terminal may send an execution command to turn on the external power supply, and execute the execution command to turn on the external power supply through the main controller 331 of the PLC control cabinet 33.
In one embodiment, the illumination of the arid region of the dry-wet alternating lakeside zone is sufficient, so that the intelligent control water diversion system can normally operate when water diversion and irrigation are needed in drought, an external power supply 37 is not provided, and the solar power generation system 36 can ensure the operation of the intelligent control water diversion system.
Before intelligent control diversion system began to operate, PLC switch board 33 at first can detecting system's operational environment satisfy: the liquid level water tank 325 has no water shortage, the vacuum pump 321 has no fault, the motor 312 of the self-priming water pump 31 has no fault, the drainage electric valve 3221 has no fault, the electric butterfly valve 41 has no fault, the water level of the reservoir 1 has not reached the lower limit (monitored by the first water level sensor), and the like; the manual gate valve 3222 is opened, the system receives automatic drainage motorised valve 3221 of opening after the start order, start vacuum pump 321, and the water-steam mixture when vacuum pump 321 exhausts passes through leading water pipeline 2, partial outlet conduit 4, intake pipe 322 and outlet duct 324 in proper order, and along with the continuation of evacuation, water in the cistern 1 is drawn up along the pipeline gradually, can start self priming water pump 31 motor 312 in theory after the self priming water pump 31 impeller is totally submerged in the aquatic. Control system increases to a take the altitude (start self priming water pump 31 if reaching 20cm water level, close vacuum pump 321) through liquid level water tank 325 water level and judges whether the self priming water pump impeller 3122 is flooded to the water column in the pipeline, then automatic start self priming water pump 31, 31 motor 312 of self priming water pump starts the back time delay several seconds, open the electric butterfly valve 41 of delivery port, electric butterfly valve 41 opens the back and closes vacuum pump 321, close drainage motorised valve 3221, open liquid level water tank 325 drainage motorised valve 328 simultaneously. So far, the whole starting process of the self-priming water pump 31 is finished. Shutdown process: under the condition that self priming pump 31 operates, the system receives the stop command after, at first self-closing water outlet's electric butterfly valve 41, then stops self priming pump 31's motor 312 again. Wherein the second water level sensor 326 in the liquid level water tank 325 functions 3: firstly, judging whether the vacuumizing is finished or not, and starting the self-priming water pump 31 after the vacuumizing is finished; secondly, the system automatically opens the drainage electric valve 328 of the liquid level water tank 325 after the self-priming water pump 31 is started, and automatically closes the drainage electric valve 328 of the liquid level water tank 325 after water is drained to a certain height such as 15cm of water level, so that the automatic drainage aims to provide a basis for finishing judgment of next pump starting drainage; and thirdly, environmental conditions during remote control of the self-priming water pump 31, namely that the water level cannot be lower than a certain height such as 10cm water level, otherwise the system cannot execute an automatic pump starting command.
A bypass gate valve 3223 connected in parallel with the manual gate valve 3222 and the electric drainage valve 3221 is arranged on the air inlet pipe 322. The intelligent control diversion system can also adopt a manual pump starting process: a selection mode switch on a panel of the PLC control cabinet 33 is switched to a 'field' position; then, after the vacuum pump 321 is started, the bypass gate valve 3223 is opened; it explains the vacuum drainage has been accomplished to wait for liquid level water tank 325 water level to reach the take the altitude after, 31 impellers of self priming water pump should be submerged to the water column in the pipeline this moment, press 31 start button of self priming water pump on the PLC switch board 33 door and start self priming water pump 31, wait for several seconds back 31 complete operation of self priming water pump, manually open electric butterfly valve 41, until electric butterfly valve 41 opens the back completely, electric butterfly valve 41 opens the pilot lamp and lights, close bypass gate valve 3223 at this in-process, then close vacuum pump 321 again. And (3) manual pump turning-off process: manually close electric butterfly valve 41, electric butterfly valve 41 closes the pilot lamp and lights, then presses PLC switch board 33 door again and goes up self priming water pump 31 stop button, stops the operation of self priming water pump 31 motor 312.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the present invention, and these modifications should also be construed as the protection scope of the present invention.
